Kat Von D and Deadmau5 call off engagement, air dirty laundry on social media

Kat Von D has a history of sharing her relationship woes on social media. Remember her infamous 2011 Facebook post about soon-to-be-ex-fiancé Jesse James that began, "Today I encountered the 19th girl to add to the list of people Jesse cheated on me with during this last year"?

"Kat and I split in November and I moved back home to Toronto," he wrote. "During this time, while we were broken up, I did have relations with another woman. Following that, Kat and I reconciled and I acknowledged being intimate with another person while we were estranged. We did move past those issues and I proposed to Kat in mid- December."

But he adamantly denies cheating on her: "At the end of June, it was clear that the relationship was not working and we mutually ended the engagement. I was not, at any point, unfaithful to Kat during our time together. I don't wish to go tit for tat with these kinds of pronouncements and don't expect to comment further, but I do believe that those who have expressed concern deserve a more complete understanding of what transpired."

Von D, for her part, is trying to look on the bright side. "Onwards and upwards," she tweeted Wednesday afternoon, followed by a photo of a heart tattoo and the advice, "Go out into the world with Love."
